UNITED STATES PATENT OFFICE.

WILLIAM II. BAKER, OF PONTIAC, MICHIGAN, ASSIGNOR OF ONE-HALF TO SAMUEL W. SMITH, OF SAME PLACE.

LAP-RING} SPECIFICATION forming part of Letters Patent No. 402,384, dated April 30, 1889.

Application filed December 17, 1888. Serial No. 293,853. (No model.)

'Ta or whom it may concern:

Be it known that I, WILLIAM I-IYBAKER, a citizen of the United States, residing at Pontiac, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Links, of which the 7 following is a specification, reference being and easily operated in all kinds of weather,

as will more fully hereinafter appear.

The invention consists in certain novel features of construction, that will be fully hereinafter set forth, and particularly pointed out in the claim appended.

Referring to the accompanying drawings, Figure 1 represents a plan view of my improved link complete; Fig. 2, a side elevation of the same; Fig. 3, a plan view of the link with the sections separated, and Fig. 4 a transverse sectional view on the line 00 w of Fig. 2. In the drawings, the letters A A designate the two sections of the link, these sections being constructed alike and cast in one piece. Each section is constructed of a central vertical disk-like portion, a, and two oppositelyprojecting horizontal rings or hooks, b b. The sections are pivoted together by a horizontal rivet, 0, passed through central apertures in the disks a, the adjacent faces of the disks being made smooth and flat to permit of a free movement of the sections.

' As shown in Fig. 3, the. pivot 0 may be formed integral or cast with one of the sections, if it is so desired. The adjacent faces of the open rings 17 are flattened, as at b, so that when the'link is closed, as in Figs. 2 and 4, each pair of open rings 1) will form one solid and strong closed ring, as shown, which will present no obstructions or weak places.

Projecting from the flattened face of each their outer faces are rounded to preserve the contour of the rings. These lugs and recesses serve to prevent the portions 1) from straightening out or breaking when subjected to great strain. These lugs also prevent the portions 17 from moving laterally upon each other.

The advantage derived from forming the lugs and recesses upon the edges of the rings 1) lies in the fact that it will be'impossiblefor any dirt or gravel to lodge in the recesses, thereby insuring at all times a closefit of the flattened portions b of the rings 1). This location of the recesses also prevents any accumulation of water or dampness, and thereby prevents the parts freezing together in cold weather.

- What I claim, and desire to secure by Letters Patent, is-

As an improved article of manufacture, a lap-ring consisting of the two sections AA, these sections being pivoted together and constructed each of a disk, at, and the oppositelyprojecting hook portions 1), having their adjacent faces flattenedand their exposed surfaces rounded, each of the said hook portions having projecting from its outer edge an integral lug, 01, these lugs fitting in recesses formed in the outer edges of the adjacent hook portions and having their outer or exposed portions rounded to conform to the contour of the rings formed by the said hook portions, substantially as herein set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM H. BAKER.
